In 2009, China's LED industry will rise against the trend, and the industry scale will reach 100 billion yuan in 2010.

The "Twelfth Five-Year Plan" will be a key period for China's semiconductor lighting technology innovation and industrial development.

The semiconductor lighting (LED) industry is one of the few strategic emerging industries in China that has mastered key core technologies, has market demand prospects, and has low resource energy consumption, large driving coefficient, many employment opportunities, and comprehensive benefits. It not only brings another revolution in the history of lighting, but also an important way to save energy and reduce emissions, and will play an important role in the development of a low-carbon economy. Faced with the huge market space and energy-saving potential of the semiconductor lighting industry, many developed countries have listed semiconductor lighting as a strategic emerging industry, and a battle to seize the commanding heights of emerging industries has begun globally. For China, the development of the semiconductor lighting industry is a major strategic choice for the future and for the long-term.

Semiconductor lighting boosts low carbon economy

Semiconductor lighting and traditional lighting and display light sources have shown good energy-saving effects in terms of light efficiency. For example, landscape lighting energy saving 70%, LCD TV backlight energy saving 50%, road lighting energy saving 40% -50%, LED indoor downlights, spotlights and other lighting products can save 50% energy compared with traditional halogen lamps, fluorescent lamps. The comprehensive cost (including the one-time purchase cost of the light source/lamp, the cost of light source replacement during the life of the lamp, the cost of power saving during the trial period of the lamp, the cost of labor service, etc.) can be equal to the traditional light source for about 3 years to 5 years. At the same time, LED does not have the problem of mercury in the cold cathode tube (CCFL), which can greatly reduce the environmental pollution of used lamps, and the LED lamps are powered by low-voltage DC, without infrared and ultraviolet radiation, and are truly green and healthy illumination sources.

Since 2009, under the impetus of the “Ten Cities and Ten Thousands” pilot demonstration application project of the Ministry of Science and Technology (hereinafter referred to as “Ten Cities and Ten Thousand Cities”), domestic power LED chips have been partially used for road lighting and indoor downlights and spotlights. Lighting is applied. Through the integration of optical design, heat dissipation, driving and other technologies, indoor and outdoor functional lighting fixtures have products with luminous efficacy exceeding 80lm/W. According to the preliminary statistics of 21 pilot cities, as of now, more than 500,000 street lamps, tunnel lights, solar LED street lights, LED fluorescent lamps, downlights, spotlights, stage lights and other products have been demonstrated and applied, saving 100 million yuan annually. More than kWh. In addition, driven by the Shanghai World Expo and the Guangzhou Asian Games, a large number of LED landscape lighting and indoor and outdoor lighting products have been widely used and socially recognized.

According to experts' prediction, in 2015, lighting power will reach 600 billion kWh (annual increase of 3%-5%), LED lamps can achieve 120lm/W, and LED lighting accounts for more than 20% of the lighting market. Saving 100 billion kWh of electricity, reducing carbon dioxide, sulfur dioxide, nitrogen oxides, dust emissions, etc., about 150 million tons, and building 21 power plants with 1 million kilowatts less, and reducing new power plants by 30% (recommended in 2015) About 63 million kilowatt power stations.) It is estimated that by 2020, the lighting power will reach 720 billion kWh, the luminous efficiency of LED lamps will reach 150lm/W, accounting for 50% of the lighting market, saving 340 billion kWh per year, and building less than 73 million kilowatts of power stations. By lighting, we do not need to add new power stations. Some experts predict that by 2015, the localization rate of chips can reach 70%, and the industrial scale will reach 500 billion yuan.

China enters a period of rapid development

Since the launch of the National Semiconductor Lighting Project in 2003, the relevant policies in the Science and Technology Research Program of the Ministry of Science and Technology and the New Materials in the 863 Program have supported the technological innovation and industrialization of semiconductor lighting. Several ministries have also arranged special funds to support them. China's semiconductor lighting industry and technology have made significant progress, initially forming a relatively complete R & D and industrial system from upstream materials, midstream chip preparation to downstream device packaging and integration applications.

1. Major breakthroughs in key technologies for industrialization. The research and development of LED manufacturing technology with enterprise as the main body is progressing rapidly.

2. The industry has begun to take shape, the industrial chain has become more and more complete, and market applications have been at the forefront of the international market. As of the end of 2009, there were more than 3,000 LED companies in China, and private enterprises accounted for 85% of the total. In 2009, the output value of China's LED chips increased by 25% compared with 2008, reaching 2.3 billion yuan; the output value of LED packaging reached 20.4 billion yuan, an increase of 10% compared with 2008; the output increased by 10% from 9 billion in 2008 to 105.6 billion. The output value of high-brightness LEDs reached 18.6 billion yuan, accounting for 90% of sales. At the same time, from the perspective of product and enterprise structure, the market for SMD (Surface Mount Device) and high-power LED packaging is growing rapidly.

3. The industrial development environment is getting better and better. The government has actively promoted the semiconductor lighting industry as a strategic emerging industry. With the improvement of product performance and energy-saving level, China's semiconductor lighting industry has entered a rising period, the market potential is huge, and the industrial upgrading is continuously promoted.

Standard strategic escort industry development

In order to promote technological integration and innovation, accelerate the process of industrialization of results, and strengthen cooperation between industry, academia and research, the National Semiconductor Lighting Engineering R&D and Industry Alliance (hereinafter referred to as “the Alliance”) has established industrial R&D funds, organized major demonstration projects for the Olympic Games, held innovation competitions, and established patents. The pool and other work have established a platform for cooperation between industry, universities and research institutes, which has improved the efficiency and level of technological innovation and promoted the implementation of major projects. Under the joint promotion of the alliance and related departments, 8 national standards and 9 industry standards have been officially released. In order to support the pilot work of “Ten Cities and Ten Thousand Miles”, the Alliance has completed five recommended technical specifications for LED road lighting products, tunnel lights and road lighting products supervision and inspection and installation acceptance rules, as well as technical specifications for cold LED road lighting products.
